Background: Infection with the lymphocytic choriomeningitis virus is a human zoonosis caused by a rodent-borne arenavirus and is often seen in autumn and winter when mice retreat into houses. Infection in humans is acquired after inhalation of aerosols or direct contact with excreta of an infected rodent.
Case Description: A 37-year-old woman was referred to St. Elisabeth hospital in Tilburg, Netherlands, complaining of severe progressive headache, nausea and vomiting. Three weeks before presentation a mouse had bitten her finger. On neurological examination there were no abnormalities. Cerebrospinal fluid investigations indicated viral meningitis. Immunofluorescence serological testing confirmed the diagnosis of lymphocytic choriomeningitis.
Conclusion: Infection by lymphocytic choriomeningitis virus after contact with rodents can cause viral meningitis. The acquired form of the disease is known to be self-limiting in immunocompetent patients.

Background: Patients with cancer are at elevated risk for tuberculosis (TB) reactivation. Diagnosis of latent TB infection and TB disease remains challenging in this patient population despite the advent of interferon-γ release assays (IGRA).
Methods: We retrospectively reviewed medical records of all patients with cancer who had IGRA testing (QuantiFERON-TB [QFT-TB] or T-SPOT.

Gastric carcinoma with lymphoid stroma (GCLS) is characterized by dense intra-and peritumoral lymphocytic infiltration and a high rate of Epstein Barr Virus (EBV) infection, suggesting being a promising candidate for immunotherapy. We investigated correlations between PD-L1 expression and clinicopathologic factors, including EBV positivity and microsatellite instability (MSI) status in GCLSs. The study included resected 214 GCLSs and 300 gastric adenocarcinomas (GACs) for control.

Long-term control of viral replication relies on the efficient differentiation of memory T cells into effector T cells during secondary immune responses. Recent findings have identified T cell precursors for both memory and exhausted T cells, suggesting the existence of progenitor-like effector T cells. These cells can persist without antigenic challenge but expand and acquire effector functions upon recall immune responses.

Canine monocytic ehrlichiosis (CME), induced by Ehrlichia canis, is an important infectious disease in dogs, characterized by various clinical signs and consequent immune dysfunction. This study aimed to characterize nuclear morphology, chromatin compaction, histone H3 acetylation, and DNA methylation in lymphocytes from dogs naturally infected with E. canis, compared with healthy controls.

A systematic review and meta-analysis were performed to evaluate the virus-specific T-cell response after COVID-19 mRNA vaccination, using the QuantiFERON SARS-CoV-2 interferon-γ release assay. A search was conducted (June 8, 2023) in the PUBMED, SCOPUS, and medRxiv databases, to identify studies reporting the QuantiFERON SARS-CoV-2 (Starter (two antigen tubes) or Starter + Extended Pack (three antigen tubes), cut-off ≥ 0.15 IU/mL) positivity rate (PR) in immunocompetent adults, following the administration of two or three COVID-19 mRNA vaccine doses.
